Strength Training Perceptions Amongst Vocational Circus and Dance Students.

Introduction: The aim of this study was to analyze perceptions of strength training in vocational circus and dance students. It was hypothesized that due to the higher relative strength demands and associated risks of working at height in some aerial and acrobatic disciplines that circus students would be more open to strength training than dancers. Methods: Eighty students completed the Training Information Survey (TIS) (Mean age = 20.74 ± 2.71); 39 circus students and 41 dance students. 97% of circus students and 69% of dance participants reported that strength training was a required part of their training with students participating in strength training 4.24 ± 0.98 and 3.05 ± 1.42 day per week respectively. Results: Perceptions of strength training amongst vocational circus and dance students appear to be favorable, with both sets of students strongly agreeing with the statements "Strength training is essential to my overall development as a dancer/circus artist" (5.00 (IQR 1.00) and 5.00 (IQR 1.00) respectively). Following Bonferonni correction only one statement returned statistically significant results with dance students agreeing more strongly with the statement "Strength training increases muscle size," U = 473.00, P = .001. Students also agreed that strength training helped them to feel better mentally and physically, that strength training is beneficial for both men and women and that it should not be designated as specific to either sex. Conclusion: Results support earlier studies that suggest a cultural shift in perceptions of strength training and ideal esthetic in dance, particularly amongst students and that they are keen to incorporate strength training into their practice. Educational establishments should note students' interest in participating in strength training, reviewing how to embed effective strength training education, more coaching and time allowance for these activities within their timetable. Further research with a greater sample size is recommended to further substantiate these indications of a shift in perceptions.

The impact of snapchat usage on drunkorexia behaviors in college women.

ObjectiveResearch has shown the deleterious effects of drunkorexia behaviors. The goal of this project was to examine the impact of college women's Snapchat usage on drunkorexia behavior frequencies and motives, through comparing one's body to others and internal drives for thinness.Participants636 college women (Study 1 N = 109, Study 2 N = 527) were recruited from a large research institution in the Southwestern U.S.MethodsParticipants completed an online survey regarding Snapchat usage, body comparison indices, drive for thinness, and drunkorexia behaviors and motives.ResultsFindings support the hypotheses that Snapchat usage impacts drunkorexia behaviors in general (Study 1), and specific drunkorexia motives (Study 2). These effects were mediated by an index of body comparisons and drive for thinness.ConclusionsCollege women may be at risk for drunkorexia due to their experiences on social media. Aspects of the platform may be pushing women toward disturbed eating habits.

Assessing the source of the photochemical formation of hydroxylating species from dissolved organic matter using model sensitizers.

Dissolved organic matter (DOM) is ubiquitous in natural waters and can facilitate the chemical transformation of many contaminants through the photochemical production of reactive intermediates, such as singlet oxygen (1O2), excited triplet state DOM (3DOM*), and hydroxylating species (˙OH and other intermediates of similar reaction chemistry). The formation mechanism of most reactive intermediates is well understood, but this is not the case for the formation of hydroxylating species from DOM. To investigate this chemistry, DOM model sensitizers were irradiated with two different probe compounds (benzene and benzoic acid) at two irradiation wavelengths (254 and 320 nm). The ability of DOM model sensitizers to hydroxylate these arene probes was assessed by measuring rates of formation of the hydroxylated probe compounds (phenol and salicylic acid). Multiple classes of model sensitizers were tested, including quinones, hydroxybenzoic acids, aromatic ketones, and other triplet forming species. Of these classes of model sensitizers, only quinones and hydroxybenzoic acids had a hydroxylating capacity. Methanol quenching experiments were used to assess the reactivity of hydroxylating species. These results have several implications for the systems tested. First, they suggest that the hydroxylating intermediate produced from hydroxybenzoic acid photolysis may not be hydroxyl radical, but a different hydroxylating species. Also, these data prompted investigation of whether quinone photoproducts have a hydroxylating capacity. These results confirm that hydroxybenzoic acids and quinones are important to the photochemical production of hydroxylating species from DOM, but the mechanism by which this occurs for these classes of sensitizers is still elusive.

Perceptions of Strength Training in Dance.

The aim of this study was to ascertain current perceptions of strength training (ST) in dance from the viewpoint of the professional dancer, dance teacher, and student dancers across dance genres. A total of 168 responses (149 females, 19 males) to the modified Training Information Survey (TIS) were analyzed for differences in perceptions of ST between dance students, professional dancers, and dance teachers. Some significant differences were found between professionals and teachers (p > 0.05) and between students and teachers (p > 0.001). In all instances, dance teachers were less likely to agree with the following: ST is essential to my overall development as a dancer, women should participate in ST, men should participate in ST, ST should be part of every training program regardless of dance style, ST is beneficial to women, and ST increases bodyweight. It is evident that perceptions of ST still vary across the dance sector, and it is postulated that further education for dancers on the role ST has to play on the development of a dancer would help to break down barriers to participation. From this investigation, it can also be concluded that the perception that dancers have a fear of muscle hypertrophy and a negative impact on aesthetics is no longer widely prevalent, although it still permeates throughout the dance sector.
